Finally have fuel from pump. Won't start after I turn off

My 65 Cuda has fuel from the pump now and runs just fine after I give it a shot of carb cleaner. Drove it around the neighborhood and it ran great, turned it off in my drive way would not start unless I sprayed carb cleaner in the carb to get it started. Car runs fine once started but if I turn it off it won't start unless I give it a shot of carb cleaner. ?????? Help
